Spreading method, spreading control method, and apparatus thereof

Embodiments of the present application disclose a spreading method, a spreading control method, and apparatuses thereof. The spreading method comprises: determining a first combined spreading code to be used at least according to first information associated with spreading by using combined spreading codes, the first combined spreading code comprising N spreading codes, and N being an integer not less than 2; and spreading N data units by using the first combined spreading code, wherein the N data units comprise at least one first unit and at least one second unit, the at least one first unit comprises data to be sent, and the at least one second unit is configured to recover the at least one first unit. The methods and apparatuses of the embodiments of the present application can effectively solve the problem of an insufficient number of orthogonal spreading codes by using combined spreading codes.
